Hi team,

Thanks for the feedback on deprecating these functions. There was support for deprecating them, but also some concerns, so the plan has changed to the following:
  • Deprecate `scipy.integrate.quadrature` (so we can reclaim the name for a more general-purpose function in the future).

This is something we try to never do. There are very few examples of us deprecating and then removing a name, and then reintroducing it with different behavior. There has to be an exceptionally good reason to do so, and I don't see one in the PR discussion (it's quite long, so I may have missed it). I can't even think of a potential reason, because the `quadrature` name isn't special enough that you can't pick a different name for whatever you want/need here.

Cheers,
Ralf

  • Introduce `scipy.integrate.gauss_quad` as an alias for `scipy.integrate.quadrature`, and point users to `gauss_quad` in the `quadrature` deprecation messages.
  • Mark  `scipy.integrate.gauss_quad` and  `scipy.integrate.romberg` as legacy functions.
We welcome additional feedback in gh-19510 (https://github.com/scipy/scipy/pull/19510).
Thanks,
Matt

Hi Team,

`scipy.integrate.romberg` and `scipy.integrate.quadrature` do not reliably hit their target accuracies, and when they do, they typically require more function evaluations and take more wall clock time than `scipy.integrate.quad` (all with default settings). This is documented in https://github.com/scipy/scipy/issues/18574#issuecomment-1703320598, which compares the accuracies, function call counts, and wall clock times on a benchmark set of ~800 integrals with known analytical solutions.

gh-19510 (https://github.com/scipy/scipy/pull/19510) proposes to deprecate these functions, suggesting `scipy.integrate.quad` as a drop-in replacement. Please let us know your thoughts either here or in gh-19510!

Thanks,
Matt
